A boom in outdoor activities and farm-gate visits is fuelling overseas tourism in Tasmania, with the island state experiencing the biggest growth in visitor numbers of any state and territory, according to new figures.

Key points:

Tasmania has experienced the biggest growth in international visitor numbers in the country, according to new figures

There were 307,000 international visitors to the state in the 12 months to September 2018

The latest figures from the federal body Tourism Research Australia show 307,000 international visitors came to Tasmania in the 12 months to September last year.

That was up from 267,000 in the previous 12 months — a 15 per cent increase.

Tourist spending also went up 13 per cent from $484 million in the year to September 2017, to $547 million in the year to September 2018.

Tasmania's reputation for high-quality food and wine no doubt also helped its popularity — the survey found dining out was the most popular activity undertaken by international visitors, with 7.8 million of them partaking nationally.

Visits to farm gates were the fastest growing activity — with 413,000 tourists looking for the experience nationally in 2018, up 13 per cent.

Attractions struggling to cater to tourists

Luke Martin from the Tourism Industry Council Tasmania said while all visitors were welcome, the boom was putting pressure on the environment.

"Those areas are jewels for Tasmania and Australia … frankly they haven't had the investment they should over time," he said.

"We're seeing about $80 million spent on Cradle Mountain.

"That will help with conservation challenges and its role of key tourism icon in northern Tasmania."

Margy Osmond from the Tourism and Transport Forum said finding ways to avoid issues like overcrowding and litter would be a major issue for the industry in the coming years.

"That will be everything from enough public transport, to sensitive areas," she said.

"Sustainable tourism is the discussion topic for the next couple of years.

"We've got more lead time than other countries so we need to work out how to protect and provide access."

On Tasmania's east coast, Glamorgan Spring Bay Mayor Debbie Wisby said the towns in her municipality, north-east of Hobart, were extremely busy.

"It puts a lot of pressure on facilities such as toilets," she said.

"I was told the other day there were 30 people lined up at the Orford public toilets."

Cr Wisby said the State and Federal Governments needed to help regional areas cope financially with the demand.

"Our general rates are for roads, rubbish and footpaths and some toilets, of course, but if we need to build many more toilets then of course we're going to need the government to assist in funding those," she said.

"They're not for our general ratepayers and residents, they're for visitors.

"If [the governments] get the extra taxes from visitation, then some of those taxes need to come into the councils to help support the infrastructure that needs to be built because as a small council we simply cant afford to do all that work."

In her resignation from politics, Kelly O'Dwyer said she feared another miscarriage in Canberra, far from home. Her announcement is shocking for more than just party-political reasons, writes Emma A. Jane.
